  • Publication number: 20150125712
    Abstract: A solution and method of treating wood to resist discoloration of the wood and the treated wood employ a polydentate monoamino carboxylic acid and/or a diakyl diphosphonic acid. The invention resists discoloration which is believed to be caused by the mobility of organic based chromophoric molecules within the wood which migrate toward the surface of the wood. Among uses of the invention, it is particularly helpful in effecting resistance to discoloration of wood being treated with wood preservatives, stains and coatings. In another embodiment, ammonium pentaborate may be employed to resist discoloration.

    Abstract: The invention relates to a process for acetylation of wood having a density of above 400 kg/m3, particularly, of Southern Yellow Pine, and acetylated wood obtainable by this method. The described acetylation process allows the production of acetylated wood having higher acetylation levels, such as an acetyl content of at least 20% by weight. The acetylated wood has also a low residual acetic acid content, in particular, lower than 1% by weight. The invention is particularly useful for acetylation on industrial scale of pieces of solid wood, preferably, of wood beams.

  • Patent number: 8846205
    Abstract: Hybrid strategies generally involve treating biodegradable substrates with preservative compositions having at least two phases in which the metal biocide is distributed among at least the two phases and via equilibrium reactions moves between the two phases. Both phases are caused to contact the substrate in a manner so that the phases are in contact with each other during at least a portion of the treatment. In illustrative embodiments, the first phase is a liquid phase comprising complexed metal biocide dissolved in a liquid carrier, while the second phase comprises particles comprising the metal biocide, often precipitated and/or colloidal particles. The strategies and related compositions, processes, and treatments are hybrid in the sense that the strategies include both heterogeneous (insoluble) and homogeneous metal biocide constituents. Unlike heterogeneous strategies, hybrid strategies are less sensitive to particle size constraints and may use biocide particles with a wider range of particle sizes.

    Abstract: The present invention relates to a method for reducing wetwood content in green lumber by a treatment with a selected fungal species, such as Phlebiopsis gigantea or Gliocladium roseum, prior to kiln drying. In the laboratory conditions, the biological treated boards reduced wood moisture content (MC) by 22-37% more than untreated boards. The time required for drying biological treated boards was approximately reduced by 10% compared with untreated controls, and by 33% compared with freshly-saw lumber. After drying, the biological treated boards reduced the total deformation with stain, warping and checking by 14-25%.

The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises N?-lauroyl-L-arginine ethyl ester (“LAE”).

    Abstract: In order to prolong the usage of wood one needs to prevent the growth of rot and fungi. The most common substances used today are not environmentally friendly and they need to be replaced by more environmentally friendly options. Water glass or sodium silicate has been known for a long time having properties which give the wood resistance to rot and fungi and in addition also fire retardant properties. The present invention discloses a method for treatment of wood to improve the flame retardant properties and also the resistance to rot, fungus, mold and insects of a wooden material. The wood treatment method of the invention comprises the steps of providing a wooden material and providing water based formulation which is stable in room temperature or in temperatures ranging from 15-35° C.

  • Publication number: 20130199276
    Abstract: Metal nano articles were incorporated into wood. Ionic liquids were used to expand the wood cell wall structure for nanoparticle incorporation into the cell wall structure. Nanoparticles of elemental gold or silver were found to be effective surface enhanced Raman spectroscopy (SERS) imaging contrast or sensing agents. Nanoparticles of elemental iron were found to be efficient microwave absorbers and caused localized heating for disrupting the integrity of the lignocellulosic matrix. Controls suggest that the localized beating around the iron nanoparticles reduces losses of cellulose in the form of water volatiles and CO2. The ionic liquid is needed during the incorporation process at room temperature. The use of small amounts of ionic liquid combined with the absence of an ionic liquid purification step and a lower energy and water use are expected to reduce costs in an up-scaled pretreatment process.

The material includes a crystal borate having a first substitutable element and a second substitutable element, one or more rare earth ions substituted for the first substitutable element, and chromium substituted for the second substitutable element. The one or more rare earth ions are selected from a group consisting of neodymium and ytterbium. The material also may include a medium within which particles of the borate are incorporated. The medium, with the luminescent material particles, may form a security feature of an article. Embodiments of methods for identifying whether such a luminescent material is incorporated with an article include exposing a portion of the article to excitation in a chromium absorption band, and determining whether a detected emission produced by the article as a result of the excitation indicates an ytterbium emission after termination of the exposing step.
